Why wouldn’t an instructor tell a student they were good when the instructor is the only meausre of the students perfomrance?

Most dangerous this is being told you’re great when you’re not

Why wounldn’t a shitty instructor say competition doen’t matter when it is the one thing that will expose him.

Why do schools say competition doesn’t matter but then watch UFC / follow GracieMag / etc?

Why do parents say they don’t want their kids fighting but then would be mad if the kids got beat up?
